Keyword driven framework is an action based test method used in planing and implementation of automation.

Data Driven Framework :

Data driven is the design of possible inputs what may be given by the end user.This would cover maximum probabilities of an input data.It can either be Spread sheet(excel)/sql/CSV.We have to connect and pass the values to the respective field or element.The
data should be designed by the experienced person on the project. It
may be a client or even non technical person but should be more familiar
from an end users prospective.We have to map the file path properly.

Hybrid Framework:

The Hybrid Automation Framework is otherwise referred to in the industry as a "Hybrid Keyword Data Driven Automation Framework".

Performance testing - It is performed to evaluate the
performance of components of a particular system in a specific
situation. It very wide term. It includes: Load Testing, Stress Testing,
capacity testing, volume testing, endurance testing, spike testing,
scalability testing and reliability testing etc. This type of testing
generally does not give pass or fail. It is basically done to set the
benchmark & standard of the application against Concurrency /
Throughput, Server response time, Latency, Render response time etc. In
other words, you can say it is technical & formal evaluation for
responsiveness, speed, scalability and stability characteristics.

Load Testing is subset of performance testing. It is
done by constantly increasing the load on the application under test
till the time it reaches the threshold limit. The main goal of load
testing is to identify the upper limit of the system in terms of
database, hardware and network etc. The common goal of doing the load
testing is to set the SLAs for the application. Example of load testing
can be:

Running multiple applications on a computer simultaneously -
starting with one application, then start second application, then
third and so on....Now see the performance of your computer.

Endurance
test is also a part of load testing which used to calculate metrics
like Mean Time Between Failure and Mean Time to Failure.

Load Testing helps to determine:

Throughput

Peak Production Load

Adequacy of H/W environment

Load balancing requirements

How many users application can handle with optimal performance results

How many users hardware can handle with optimal performance results

Stress testing - It is done to evaluate the
application's behaviour beyond normal or peak load conditions. It is
basically testing the functionality of the application under high loads.
Normally these are related to synchronization issues, memory leaks or
race conditions etc. Some testing experts also call it as fatigue
testing. Sometimes, it becomes difficult to set up a controlled
environment before running the test. Example of Stress testing is:

A banking application can take a maximum user load of 20000
concurrent users. Increase the load to 21000 and do some transaction
like deposit or withdraw. As soon as you did the transaction, banking
application server database will sync with ATM database server. Now
check with the user load of 21000 does this sync happened successfully.
Now repeat the same test with 22000 thousand concurrent users and so on.

Spike
test is also a part of stress testing which is performed when
application is loaded with heavy loads repeatedly and increase beyond
production operations for short duration.
